(free_vnode()). Upon freeing, the file cache is now only written back if the
file is not deleted.
dec_vnode_ref_count() no longer frees vnodes that are not going to be deleted.
Instead, it will add them to an unused vnode list, so that they can be freed
if needed (currently only 512 unused vnodes will be kept around). This should
speed up the whole thing, and makes the file cache much more useful, as it's
no longer dumped after the file is closed.
fs_unmount() is not yet respecting this (ie. it doesn't free those nodes as
it should).

Also implemented a get_bios32_service() function which you can use to get
access to that service (ie. for use by the PCI bus manager).

done.

bfs_open_dir() now checks for read access.
bfs_lookup() now checks for execute access and not read access anymore
(as reported by Ingo as well).

Inode::Create() now checks for write access to the inode when O_TRUNC is set.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10271 a95241bf-73f2-0310-859d-f6bbb57e9c96
aspace_id is now defined in vm_types.h only, as it's only used internally anyway.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10261 a95241bf-73f2-0310-859d-f6bbb57e9c96
Ceccherini for the hint.
The first port ID is now 1 and not 0 anymore.
Added a first free slot hint to speed up port creation.
Added more debug output when tracing is enabled.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10260 a95241bf-73f2-0310-859d-f6bbb57e9c96
BeOS supports this as well, at least it's not documented in the BeBook
(but it's useful anyway).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10259 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed _user_set_tzspecs() to _user_set_timezone().
Renamed sTzFilename to sTimezoneFilename.
Moved rtc_print() into rtc_debug().
Fixed changing system_time_offset; since this is a shared 64 bit value,
we have to use atomic calls when we change it.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10253 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added "safemode" and "shutdown" commands.
Now makes a symlink from "more" to "less".
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10238 a95241bf-73f2-0310-859d-f6bbb57e9c96
and only the syscall is exported.
For now, it always returns B_ENTRY_NOT_FOUND - since the boot loader
does not have support for driver settings yet.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10237 a95241bf-73f2-0310-859d-f6bbb57e9c96
_kern_get_safemode_option() just returns the driver_settings parameter
string, so it has to be evaluated by the caller.
Also, "safemode" returns 1 if safemode is enabled.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10236 a95241bf-73f2-0310-859d-f6bbb57e9c96
Improved argument parsing code - you no longer have to specify each option separately.
Improved time parsing for the "-d" option: it's now possible to add a unit to the
time value ("m" or "s"), and you don't have to add a space anymore (ie. -d5 will
work, too).
Cleaned up the source file to better match our style guide, and look better overall.
Also added a comment about the usefulness of some of the options here - I think
we should remove the alert stuff again; one requester (in Roster) is really enough
for my taste.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10234 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added _user_shutdown() and made it available as syscall.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10233 a95241bf-73f2-0310-859d-f6bbb57e9c96
When you specify this directory, no image file will be created.
Added the listarea command.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10222 a95241bf-73f2-0310-859d-f6bbb57e9c96
Implemented F_DUPFD support for fcntl() - we no longer see any redirection errors when
booting into Haiku.

bus manager from the floppy image - it's not really needed yet, and with
all the debug output, it cuts some 300 kB from the final image.
If you're floppy image did not work anymore in Bochs, try now.

_user_create_area() and _user_clone_area() now inherit the read/write protection
for the kernel, too - before, it was always mapped read/write in the kernel,
but there is no reason to do that.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10214 a95241bf-73f2-0310-859d-f6bbb57e9c96

an off_t as size argument.
Implemented new function vm_cache_write_modified() which will write all
dirty pages of this cache back to disk (using the new vm_page_write_modified()
function).
Fixed warnings when compiled with debug output.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10205 a95241bf-73f2-0310-859d-f6bbb57e9c96
pages in a cache back using the store's write method. Doesn't optimize
disk access yet.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10204 a95241bf-73f2-0310-859d-f6bbb57e9c96
While we can tolerate the device driver to ignore the bytes argument when we
read from the device, we cannot do this for writes - now the code actually
takes this into account. Also added a comment about what to do when our own
driver is fixed :)
Implemented file_cache_sync().
file_cache_set_size() now uses vm_cache::virtual_size instead of the now
removed vnode_store::size. Also, it now resizes the vm_cache as well, so
that any no longer used pages are freed.
write_to_cache() now puts all pages in the modified list, so that they
can be written back easily.
Improved debug output.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10203 a95241bf-73f2-0310-859d-f6bbb57e9c96
vm_cache::virtual_size is now used by the file cache code.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10202 a95241bf-73f2-0310-859d-f6bbb57e9c96
dec_vnode_ref_count() now deletes the cache *after* calling the file system's
remove/release vnode function. Also, it will now write back any pending
changes in that cache before removing it.
Some cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10201 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed size argument of vm_cache_resize() from size_t to off_t.

Now, it will only notify the read requests do gather the data.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10198 a95241bf-73f2-0310-859d-f6bbb57e9c96
Inode::SetFileSize() now changes the size of the cache as well.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10197 a95241bf-73f2-0310-859d-f6bbb57e9c96
That avoids starting a new transaction for no reason (which wouldn't do any harm,
but still, it's not necessary to do that at all).
log_entry::cached_blocks is no longer maintained or needed.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10185 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also, it did not check the access permissions if the file already existed.
Removed check for INODE_NO_CACHE, as this no longer applies.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10182 a95241bf-73f2-0310-859d-f6bbb57e9c96
Moved test main() into separate file under tests/.
Fixed warnings, some cleanup.

stuff belongs to userland), they are completely broken, too.
As a quick hack, they no longer disable interrupts, so that the env memory
can be accessed almost safely (in case its valid memory at all).
Please don't fix this, but remove those functions from the kernel.

Improved "thread" debug output to have all data values at the same column.

(thinks like "cat x | grep y", or "a=`uname -m`) - they now do.
Added more debug output.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10060 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10054 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Ported over BFS to the new cache API
- Inode no longer inherits from CachedBlock, and therefore, no longer
keeps the whole inode block in memory. It now has a copy of the bfs_inode
structure in memory instead. This has a number of advantages but also some
disadvantages, so it might be reverted later, even if it's unlikely.
- Added a NodeGetter class that can be used whenever the real block needs
to be accessed (ie. for attributes)
- Changed *transaction to &transaction where possible
- Removed support for KEEP_WRONG_DIRENT_RECLEN
- Removed support for uncached file access since that's no longer needed
- Fixed some endian issues in bfs_write_stat()
- Removed the install BFS rules, since they don't make any sense anymore
(unless you are running Haiku ;-))
Note, logged streams are not supported anymore right now. Also, the
transaction code is pretty simple and slow - it will be improved later
on. Attribute code is pretty much untested in the new environment.

R5 compatible version still has this support).
Added a missing const to block_run::IsZero().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10049 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added API for sub transactions (not yet implemented).
Added file_cache_sync() function.

not everything is in this one file.
Removed definition of STD_INSPIRED: this not only fixes some warnings, it
also removes functions that are not exported under BeOS, and there is no
reason to change that.
Added weak export of timelocal() in case STD_INSPIRED is not defined in
localtime.c.
